WRENCH.

SPECIFICATION forming part of Letters Patent No. 793,503, dated June 27, 1905.

Application filed December 8, 1904. Serial No. 236.027.

To (bl/Z whom, it may concern:-

Be it known that I, HARRY I-I. BoUssnR, a citizen of the United States, residing at Halstead, in the county of Harvey and State of Kansas, have invented certain new and useful Improvements in Wrenches, of which the following is a specification.

This invention relates to improvements in wrenches of that type embodying, essentially, a shank provided with a suitable handle and having a nut-receiving socket for cooperation with a nut or like part in removing or applying the same.

The invention aims to provide a wrench of this class having adjustable parts admitting of use of the wrench in operating nuts of various sizes, thereby broadening the application of the invention in an obvious manner.

The invention further consists in the provision of peculiar means for operating or turning the wrench to facilitate the actuation of a nut with greater case than incident to the use of the majority of wrench devices at pres ent used. I

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and accompanying drawings.

WVhile the invention may be adapted to different forms and conditions by changes in the structure and minor details without departing from the spirit or essential features thereof, still the preferred embodiment thereof is shown in the accompanying drawings, in which- Figure 1 is a perspective view of a wrench embodying the essential features of the invention. Fig. 2 is a vertical longitudinal sectional view. Fig. 3 is a detail perspective view of the adjustable socket member. Fig. 1 is a partial vertical sectional view showing an adjustable socket member in a position assumed thereby when in use.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The wrench comprises, essentially, a shank 1, provided at one end with a handle 2 and at its opposite end with a nut-receiving socket 3. The end of the shank 1 having the socket 3 is somewhat enlarged, as shown at 4, in order to lend the necessary substantiality to the structure. The enlarged portion 4 of the shank is preferably of square formation, though this is not essential. In order that the wrench may accommodate nuts of different sizes in its actual use, a supplemental socket member 5 is adjustably mounted upon the enlarged portion 4 of the shank 1. The member 5 is of tubular formation and snugly receives the enlarged portion 4 of the shank 1, being adapted to be adjusted so that its outer end will come about flush with the outer end portion of the socket 3 when said part 5 is not being used. WVhen the socket 3 is found to be too small for operating a nut, adjust ment of the member 5 will project the outer end portion thereof outwardly beyond the outer extremity of the socket 3, whereupon an auxiliary socket 6 will be formed, as shown in Fig. 4. The socket member 5 is prevented from displacement by means of a threaded stem 7, projecting from the inner extremity thereof and preferably integrally formed therewith. The stem 7 passes through an ad justing-nut 8, which latter is partially received in a recess 9, formed in a side of the enlarged portion 4 of the shank 1.

Ordinary socket-Wrenches of the type to which this invention relates are not designed to be used in removing nuts which have been screwed upon a bolt or like part beyond the extremity thereof, and it is therefore contemplated to construct my wrench in such a manner that the same may be readily used upon belts or like parts under similar conditions to those mentioned above. In accomplishing the above the inner extremity of the socket 3 of the shank 1 merges into a recess or bore 10, which extends some distance longitudinally of the shank 1. The bore or recess portion 10 is designed to receive the extending end portion of the bolt upon which a nuthas been screwed, the nut itself being received in the socket 3. When the adjustable socket member 5 is being used, it will be understood that the socket 8 forms virtually a bore or recess portion for the part 5 in virtually the same manner as the bore 1.0 and performs a like function with regard to the socket 8.

The handle 2 of the wrench is peculiarly mounted thereon, being provided with an extension 11, formed with a socket adapted to receive a head 12, formed upon the end of the shank 1 opposite the socket 3. The handle is secured to the shank l by means of a suitable fastening 13, and the parts 11 and 12 afford a swivel connection between the handle and shank, permitting revolution of the shank in operating the wrench, while the handle is held longitudinally in proper position. In other Words, the handle 2 is not utilized to turn the wrench, but a lever or bar 14 is provided for this purpose, said bar passing through the shank at a point between its ends, as shown at 15. The bar 14 is adapted to be engaged by a set-screw 16, mounted upon the shank 1 so as to be held in an adjusted position. The part 14 is provided at its ends with balls or weights 17, forming a means for grasping the bar and at the same time assisting the turning of the shank under certain conditions of service.

In the actual use of the wrench the socket 3 or member 5 is engaged with a nut and the handle 2 is grasped to hold the shank 1 in proper position for actuating said nut. The

bar 14 is now adjusted upon the shank, so as to give greater or less leverage in removing or securing the nut in place, as necessary. If the bar 14 is so adjusted that the shank is about central thereof, it will be noted that I said bar may be readily actuated, so as to revolve, under which condition the weights 17 are advantageous in securing a continuous revolution of said shank and quickoperation of the nut in a desired direction.

The wrench device is very simple and may be used to great advantage in facilitating the operation of nuts or like parts in a manner clearly apparent.

If in the use of the invention a full circling movement of the lever 14 cannot be given, it will be noted that this member may slide from end to end and the lever given a partial turn only. The wrench may of course be made in various sizes suitable for all kinds of work. It will be understood that the socket 3 of the shank 1 may be readily utilized to receive the shank of a bit for drilling or Woodworking purposes, the wrench device being thereby adapted to be converted into a brace or to accomplish the same function as a brace in this connection.

Having thus described the invention, what is claimed as new is A wrench comprisinga shank provided with a nut-receiving socket at one end thereof, a tubular supplemental socket member receiving the shank, a threaded stem projecting from the inner extremity of the socket memher, and an adjusting-nut mounted upon the stem aforesaid for effecting adjustment of the socket member, the shank being provided with a recess receiving the adjusting-nut.

In testimony whereof I afIiX my signature in presence of two witnesses.
